Pratica della geometria sul terreno
Pratica della geometria sul terreno is a 1758 Italian treatise on practical land surveying, published from the plates of Giorgio Fossati and drawn from the work of Sébastien Le Clerc for surveyors and students of geometry. Its pages are dense copperplate sheets of numbered geometric diagrams: circles inscribed with triangles and polygons, angled construction lines, and labelled points, which a designer could borrow as precise schematic linework and layout grids.
